Technical details

A missing authorization vulnerability (CWE-862) in the JSON-RPC API endpoint allows authenticated users to bypass privilege checks and escalate their access level. The vulnerability requires valid authentication credentials but no special user interaction; an attacker sends a specially crafted JSON-RPC request to elevate privileges. This is a post-authentication privilege escalation in the API component affecting management and cloud versions.
